The Gauss map on a class of interval translation mappings [PDF]

open access: greenIsrael Journal of Mathematics, 2002
We study the dynamics of a class of interval translation map on three intervals. We show that in this class the typical ITM is of finite type (reduce to an interval exchange transformation) and that the complement contains a Cantor set. We relate our maps to substitution subshifts.

On the Gauss maps of singular projective varieties [PDF]

open access: bronzeJournal of the Australian Mathematical Society, 2002
AbstractHere we study the dimension δ(m, X) of the general fibers of the m-Gaussian map of a singular n-dimensional variety X ⊂ Pn. We show that for all integers a, b, c, d with n ≦ a < b ≦ c < d ≦ N − 1 and a + d = b + c we have δ (a, X) + δ(d, X) > δ(b, X) + δ(c, X).

Surfaces with $1$-type Gauss map [PDF]

open access: bronzeKodai Mathematical Journal, 1996
The author proves the following theorem. Let \(M\) be an orientable connected surface of Euclidean 3-space \(E^3\). Then \(M\) has 1-type Gauss map if and only if \(M\) is an open part of a sphere or an open part of a circular cylinder. Reviewer's remark: Compact submanifolds of Euclidean spaces with 1-type Gauss map were completely classified in ...

Harmonic Gauss maps [PDF]

open access: yesPacific Journal of Mathematics, 1989
A construction is given whereby a Riemannian manifold induces a Riemannian metric on the total space of a large class of fibre bundles over it. Using this metric on the appropriate bundles, necessary and sufficient conditions are given for the Gauss map and the spherical Gauss map to be harmonic.

SUBMANIFOLDS WITH BIHARMONIC GAUSS MAP [PDF]

open access: yesInternational Journal of Mathematics, 2010
We generalize the Ruh–Vilms problem by characterizing the submanifolds in Euclidean spaces with proper biharmonic Gauss map and we construct examples of such hypersurfaces.

On Separable Higher Gauss Maps [PDF]

open access: yesMichigan Mathematical Journal, 2019
We study the $m$-th Gauss map in the sense of F.~L.~Zak of a projective variety $X \subset \mathbb{P}^N$ over an algebraically closed field in any characteristic. For all integer $m$ with $n:=\dim(X) \leq m < N$, we show that the contact locus on $X$ of a general tangent $m$-plane is a linear variety if the $m$-th Gauss map is separable.

The Gauss map of minimal surfaces in the Heisenberg group [PDF]

open access: yes, 2010
We study the Gauss map of minimal surfaces in the Heisenberg group $\mathrm{Nil}_3$ endowed with a left-invariant Riemannian metric. We prove that the Gauss map of a nowhere vertical minimal surface is harmonic into the hyperbolic plane $\mathbb{H}^2 ...

On the Gauss map of ruled surfaces [PDF]

open access: yesGlasgow Mathematical Journal, 1992
Let M2 be a (connected) surface in Euclidean 3-space E3, and let G:M2→S2(1) ⊂ E3 be its Gauss map. Then, according to a theorem of E. A. Ruh and J. Vilms [3], M2 is a surface of constant mean curvature if and only if, as a map from M2 to S2(1), G is harmonic, or equivalently, if and only ifwhere δ is the Laplace operator on M2 corresponding to the ...
